at the inauguration of president obama, she hit right back with her powerful voice. >> it was the show stopping moment on a day of political theater. it was not what it seemed. yes, that is beyonce possible is, but she now admits that it was pre-recorded. take two was live. an attempt by the senate to make amends and to explain. >> i did not have time to rehearse with the orchestra. it was a live television show and a very very important show for me. one of my proudest moments. due to the weather, due to the delay, due to no proper sound check, i did not feel comfortable taking a risk. >> a multiple choice of explanations and she insisted she had at least some along to the backing track. then, the burning question, would she be singing live at the super bowl? >> i will absolutely be singing live. i am well rehearsed and i will absolutely be singing live. this is what i was born to do. >> determination and redemption. the watching journalists loved it. will america agree? >> well, i was there on inauguration day and i thought it sounded pretty good even if it was lips sink. good luck to her, of course.
